LOOSE-LEAF BINDER.

binder which will hold the leaves as it per-` manently bound and whichmay at the same time be readily i'nanipulated so as to permit ot removalof any one or all of the leaves; interchange ol leaves, or the insertionof o new leaves.

A further object of the invention is to provide a binder which willlirmly and securely hold a greater or less number of leaves and whichwill automatically adapt itself to the bulli of the leaves as they areremoved.

Further the invention aims to provide novel means for holding thespring-pressed gripping leal ot' the binder away from the leaves so thatit will not interl'ere with the removal or insertion of leaves.

ln the accon'ipanying drawing Figure 1 is a perspective view of thebinder embodying the present invention, the gripping leat thereof beingshown raised out ot' engagement with the leaves `to be held; Fig. 2 is aplan view ot' the binder with the gripping leal in engagement with theloose leaves; Fig. 3 is a view in side elevation and partly in sectionot' the bach portion o1 the binder; Fig. ft is a view partly in sideelevation and partly in longitudinal section of the binder closed.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views ol the accompanying drawing'by the same reference characters.

In the drawing the binder is illustrated as including covers one ofwhich is indi iated by the numeral l and the other by the nnmoral 2,these covers being connected by a suitable back 3 which may be flexibleor still", as desired. The leaves to be held are indicated by thenumeral 4 and each is formed with two or more spaced openings 5 locatednear the upper edge of the leali.

rlhe binder proper consists essentially of a fixed member with which theleaves are assembled and a spring-pressed gripping member which isarranged to bear firmly against the stack of leaves and hold the sameSpecification of Letters Patent.

in` place. 'The first mentioned member is formed from sheet metal andincludes an attaching portion (i which at its rear edge is termed withan upstanding llange 7. Rivets 8 are secured through the attachingmember 6 and through the cover 1 ol the binder and `the llange 7 is sopositioned as to be covered and concealed by the back 3 when the binderis closed. The flange T is lormed at intervals at itsupper end withpintle lugs 9 and the gripping leal of the binder which constitutes thesecond mentioned member thereotl is in the :t'orm oit' a plate 10provided at its lower edge with pintle lugs ll which engage betweenpintle lugs t), a hinge pin 12 being inserted through the said pintlelugs t) and l1. One or more springs 13 are arranged upon the hinge pin12 and coiled thercabout and one end ol each spring is engaged with thellange 7 as indicated at lll and its othei end bears against theioutersido oll the plate l as indi ated at 15. '.lhesc springs tend toforcibly hold the gripping lea't 10 in engagement with the uppermostleal ol' the stack 4.

In order that the leaves may be securely held in place, posts 1li aresecured at their lower ends to the attaching portion G of the firstdescribed member ol the binder and project upwardly and through theopenings in the stack oit leaves fl; and the gripping leaf l0 is :formedwith openings 17 in which the upper ends of the posts are arranged toengage when the leal is in gripping engagement with the loose leavesll,as clearly shown in Fig. 4l oit the drawing.

As beit'ore stated, means is provided for holding the gripping leal outol engagement with the loose leaves and in such position that it willnot interfere with the removal or insertion ol the leaves land thismeans consists ol an arm 1S which is pivoted as at 19 to the rear sideof the flange 7 and has at its tree end a linger piece 2() which may begrasped :tor the purpose ol swinging the linger upon its pivot. This arm18 is provided adjacent to its said lree end and beside the linger pieceQ0 with a hooked tinger 2l which may be brought into engagement over theupper or tree edge ol" the gripping leal by tirst swinging this lealupon its hinge and then moving the arm 1S upon its pivot 19.

From the foregoing it. will be readily understood that when it isdesired to remove or insert leaves, the gripping leaf 10 is swung Sti upagainst the tension of the springs 13 and the arm 18 is then swung toposition with its finger 21 engaged with the free edge of the said leaf10. The leaf will at such time be supported in substantially the sameplane as the flange T and will when in such position in no way interferewith manipulation of the leaves t. in order to close the binder it isonly necessary to swing the arm 18 to theV rightl in F ig. 1 of thedrawing, whereupon its finger 21 will be broughtout of engagement Vwiththe leaf 10 and the latter will be automatically swung down by thesprings 18 so as to bear against the uppermost leaf 1. Jifter this hasbeen done the arm 18 may be swung to the left in said Fig. 1 so as tolie behind the flange 7, in which position it will not interfere withthe closing of the cover 2.

Having thus described the invent-ion what is claimed as new is: o

1. ln a binder of th-e class described, a fixed member, a thereto, aspring yieldably holding said gripping member iii engagement with leavesdisposed between the members, and an arm pivoted upon the fixed memberand having a hooked finger arranged for engagement with the grippingmember, whereby to hold the latter' out of such engagement with the saidleaves, the arm being adapted to be swung upon its pivot to lie besidethe iixed member or to extend beyond the said member and in position toengage with the gripping member.

2. In a binder of the class described, a fixed member, a gripping memberhinged thereto, a spring yieldably holding said gripping member inengagement with leaves disposed between the members, anA arm pivoted tothe fixed member and having a finger piece at its free end, and a hookedfinger located at the said free end of the arm and arranged forengagement with the gripping member, whereby to hold the latter out ofsuch engagement with the said leaves, the

gripping member hinged arm being adapted to be swung upon its pivot tolie beside the fixed member or to extend beyond the said member and inposition to engage with the gripping member.

3. ln a binder of the class described, a fixed member having angularlypositioned wings, one of said wings constituting an attaching means, agripping leaf hinged to the other wing of the said fixed member, a

spring yieldably holding the gripping leaf in gripping engagement withleaves disposed between the same and the att-aching wing of the iixedmember, and means carried by the second mentioned wing of the fixedmember and engageable with `vthe gripping leaf, whereby to hold the sameout of gripping engagement with said leaves.

t. ln a binder of the class described,'a

fixed member, a gripping member hinged thereto, means yieldably holdingthe gripping member in engagement with-the leaves disposed between themembers, an arm pivoted to the back of the fixed member and arranged toswing transversely thereof where.

is swunO to extend u wardl at an an le the hooked finger having itsterminal so located that when the armis swung Vto vertical position, itwill disengage from the said hinged gripping member.

edge of the hinged gripping member when` ln testimony whereof l affix mysignature in presence of two witnesses.
